Umm, how so?
Those tests are pretty damn simple. If there are any conditionals
left by the time DOM3 is complete, then we've missed an optimization
and we've missed it badly.
Can you, or someone, send me the dump files on one of the affected
platforms?
-fdump-tree-all-blocks-vops-stats
Just tar up the mess and pass them to me directly.
